Brianna Cross 10/28/16 Chemistry Essay Arsenic Arsenic is one of the most toxic elements that can be found on Earth. Arsenic has a symbol of As and an atomic number of 33. It is a metalloid which gives it both metal and nonmetal characteristics. Arsenic has many allotropes, but the gray form is important for industry. The three main allotropes are metallic gray, black, and yellow. Gray arsenic is brittle and has a low hardness (based on the Moh’s hardness scale) yet a high density. Yellow

Titanium is chemical element, with number 22 as its Atomic Number, while its Mass Number is 47.867. Titaniums symbol on the periodic table is simply Ti, it is a transition metal, and is one of the strongest metals in the world. Titanium has low density which is 4.54 g/cm3, meaning it is a good conductor of electricity, titanium has a basic silver colour. Titaniums melting point is 1660 °C, while its boiling point is 3287 °C. Titanium has a Hexagonal Crystal Structure, which is common. The hexagonal

Lives of the people will never be the same without metals. Nature entices man to explore more about metallurgy by discovering a metal that appears to be gold that has an almost magic charm, which easily captivates the people's eyes. Acquiring gold is definitely easy for the people since it can be found in free or native places (Gascoigne, 2001). During that time, people have already discovered another metal, which can be formed into various shapes but is quite harder than gold. That metal is called

pure iron and more resistant to corrosion. Iron was replaced with Bronze in tools and weapons from 1000 BC. This was the result of Iron’s abundance compared to copper and tin rather than any inherent advantages of

No one knows how costly it can be to repeatedly replace tools and parts better than the experts from R A Heller Co. in Cincinnati, OH. But don't be disheartened, their hard chrome plating services can breathe new life into your tools and machinery, keeping them in great condition for years to come. If you feel like you're throwing money out the window every time you're forced to replace a part or expensive set of tools, hard chrome plating is a great option for you. Here are a few more of the benefits

Non-ferrous metals were the first metals used by humans for metallurgy. Gold, silver and copper existed in their native crystalline yet metallic form. These crystals, though rare, are enough to attract the attention of humans. Less susceptible to oxygen than most other metals, they can be found even in weathered outcroppings. Copper was the first metal to be forged; it was soft enough to be fashioned into various objects by cold forging, and it could be melted in a crucible. Gold, silver and copper

The first video I chose is called the Search for Signs of Life on Mars. It had an interdiction by NAI Director of the Presenter Abigail Allwood. Her background was given, studied at Macquarie University in Australia, and was recruited by JPL as soon as she graduated. The topic was introduced, which is PIXL (Planetary Instrument for X-ray Lithochemistry) and the Mars 2020 Rover. The Mars 2020 Rover will be sent to Mars to seek potential clues to past life and to hopefully gather samples for possible

Iron is the first element in the eighth column of the periodic table. It is classified as a transition metal. Iron atoms have 26 electrons and 26 protons with 30 neutrons. It is the sixth most abundant element in the universe. It is a fairly soft, grayish metal. It is very reactive and will corrode or rust when exposed to moisture and oxygen. It is the most naturally magnetic of the elements. Iron becomes significantly harder when alloyed with other elements such as carbon. Iron is the most abundant

Aluminium is extracted from the metal ore bauxite. Bauxite is mined in various mines across Australia. There are two bauxite mines currently operating in Alcoa, Western Australia. These mines are the Huntly mine, located near Dwellingup and the Willowdale mine located east of Waroona. Mining and Extraction process of Aluminium Aluminium is mined on the surface of the crust. The extraction is done by electrolysis. Aluminium oxide has a high melting point at over 2 000°C, as a result it is expensive

Molycorp, Inc., one of the U.S.’s producers of materials that are needed for various products sold inside and outside of the states, had filed for bankruptcy. Their proposal was to file for liquidation of assets and then wait for the costs associated with production to decrease before they’d reorganize. The corporation manufactured rare materials that were utilized in electric cars and wind turbines. The company demonstrated the complexity of the abrupt rise and fall of their market throughout the
